1. The Danish Energy Performance Certificate Ole Michael Jensen, Aalborg University
Delegation from Styria - 11th of June 2018
State of Green. Vesterbrogade 1E, 1620 Copenhagen

2. The Danish Energy Performance Certificate
EU Energy Performance Building Directive
Danish Principles
User access
Scientific use of EPC data
Identification of energy renovation opportunities
I have grouped the topic of the day into this five issues
SBi – 16/11/2018

3. 1. Energy Performance Building Directive The EU EPC legislations
1997
Danish EPC
Adopted
2002
Implementation
2006
Recast
2010
Revision
2018
1998
Austrian EPC
EPBD
A Danish EPC has been issued since 1997, an Austrian since 1998 (in some Ländern)
SBi – 16/11/2018

4. 2. Danish principles Asset rating
Asset rating: Building registration, building data collection and computation/calculation of each individual EPC rating
SBi – 16/11/2018

5. 2. Danish Principles Six stairs off complexity: Costs and quality
Six ‘stairs’ of costs. Full operational rating starts from stair 2 and full asset rating from stair 5.
SBi – 16/11/2018

6. 2. Danish Principles National EPC Data base
All data are being collected in one central data base
Danish Energy Agency manages the base
Secretariat carries out quality control and suggest thresholds for allowing data into the base
Data divided into three general groups
General data to identify building and EPC auditor
Data for calculation of EP
Results of certification and energy savings proposals
SBi – 16/11/2018

7. 3. User access The Danish EP Certificate
Actual energy rating
Potential energy rating
New buildings
SBi – 16/11/2018

8. 3. User access Find your energy rating
Saving annually € 5000

9. 4. Scientific use Energy saving potentials
20 %
Energy saving potential Total: 35 PJ
15 PJ
9 PJ
4 PJ
3 PJ
6 PJ
Profitable energy saving (payback time: 15 years

10. 4. Scientific use Increasing energy efficiency
Building code requirements
Better insulation
Low energy windows
Air-change control
EPC calculaton
KWh/m2
Renewables
Dispersion
Year of construction
SBi – 16/11/2018

11. 4. Scientific use Market response
Sales prices for single-family houses in the years 2007–2012.The average sales price of properties with energy performance rating G with 2007set to index 100
SBi – 16/11/2018

12. 4. Scientific use (new project) Impacts of campaigns
Average ceiling insulation thickness for houses built before 1996 by year of issue, i.e. date of reporting of the individual energy label
Area-weighted U-value for windows for houses built before 1996 by year of issue, i.e. date of reporting of the individual energy label

13. 5. Identification of energy renovation opportunities
